Echinococuss granulosus (continue)
Anticipatory
What is the commonest parasitic cyst which
affects the liver?
Objectives
- To list drugs which treat this infection.
- To know epidemiology, prevention and control of this infection.
Treatment
- Surgical removal.
- PAIR i.e. Percutaneous Aspiration Injection (of hypertonic saline or other scolicidal fluid e.g hydrogen peroxide or ethanol) and Reaspiration. Cyst puncture is done under sonographic or CT guidance.
- Medical treatment → Albendazole to be repeated up to 12 cycle.
↓
→ Praziquantel.
Epidemiology
Infection with hydatid cyst depends upon:
- Intimate contact of human with infected dogs.
- Eggs dispersal and survival as transmission is hand to mouth.
- Eggs are obtained from the soil or fur of dogs or through vegetables and water.
Prevention and Control
- Proper disposal of infected viscera in slaughter houses.
- Elimination of stray dogs.
- Periodic examination of pet dogs and treatment of infected ones by Praziquantel.
- Man should avoid dogs and prevent children from handling or playing with them.
- Protection of food and drink from being contaminated with dog faeces.
